NRC Initating Five New Space-Related Studies

NRC Initating Five New Space-Related Studies

The National Research Council (NRC) is about to begin five new space-related studies.  Two are for NASA, two for the Department of Defense (DOD), and one for the U.S. Geological Survey (USGS).  The provisional memberships of three of the five study committees are open for comment at the website of the National Academies, of which the NRC is part. 

The five studies are:

Euclid is the European Space Agency’s (ESA’s) dark energy mission.  An earlier NRC study, the decadal survey for astronomy and astrophysics — New Worlds, New Horizons — recommended that NASA build a spacecraft to investigate dark energy (labeled “dark” because scientists do not understand what it is) as well as search for exoplanets and conduct surveys of the universe in the infrared region of the spectrum.   That spacecraft, the Wide Field InfraRed Survey Telescope (WFIRST), will be delayed, however, because of NASA’s constrained budget and the decision that completing the over-budget James Webb Space Telescope is an agency priority.  ESA is moving ahead with its plan for its Euclid dark energy mission and U.S. scientists would like to be part of it.   The NRC study will “determine whether a proposed NASA plan for a U.S. hardware contribution to the European Space Agency (ESA) Euclid mission in exchange for U.S. membership on the Euclid Science Team and science data access is a viable part of an overall strategy to pursue the science goals (dark energy measurements, exoplanet detection, and infrared survey science) of the New Worlds, New Horizons report’s top-ranked, large-scale, space-based priority: the Wide Field InfraRed Survey Telescope(WFIRST).”  The study will be conducted under the auspices of the Space Studies Board (SSB) and the Board on Physics and Astronomy (BPA).  The provisional membership list is available here.

DOD has requested the NRC to review and assess an Air Force concept for a reusable launch vehicle.  The NRC study will “review and assess the SMC/AFRL concept for a Reusable Booster System (RBS) for the U.S. Air Force.  Among the items the committee will consider in carrying out this review are: the criteria and assumptions used in the formulation of current RBS plans; the methodologies used in the current cost estimates for RBS; the modeling methodology used to frame the business case for an RBS capability including: the data used in the analysis, the models’ robustness if new data become available, and the impact of unclassified government data that was previously unavailable and which will be supplied by the USAF; the technical maturity of key elements critical to RBS implementation and the ability of current technology development plans to meet technical readiness milestones.”  The study will be conducted under the auspices of the Aeronautics and Space Engineering Board (ASEB) and the Air Force Studies Board (AFSB).  The provisional membership list is available here.

DOD also asked the NRC to “assess the astrodynamic standards established by Air Force Space Command (AFSPC) and their effectiveness in meeting mission performance needs, as well as possible alternatives.  The Joint Space Operations Center (JSpOC) uses astrodynamic algorithms to perform satellite orbit determination and prediction in order to maintain a catalog of over 20,000 objects, ranging from active satellites to tiny pieces of orbital debris. AFSPC established this set of astrodynamic algorithms as standards to be used in operational space surveillance mission systems. These standards were implemented to achieve interoperability between the JSpOC and the mission systems and to ensure mission performance.”  The study will be conducted under the aupices of the AFSB, ASEB, and Board on Mathematical Sciences and Their Applications.  The provisional membership of this committee has not yet been posted on the NRC website.

At the request of NASA, the Board on Health Sciences Policy, part of the Institute of Medicine (another component of the National Academies), will conduct a study that will review “the scientific merit assessment processes used to evaluate NASA Human Research Program’s directed research tasks.  The study will include a public workshop focused on identifying and exploring best practices in similar peer-reviewed applied research programs in other federal government agencies. The study will also evaluate the scientific rigor of the NASA processes and the effectiveness of those processes in producing protocols that address programmatic research gaps.”  The provisional membership list is available here.

The U.S. Geological Survey (USGS) has asked the NRC to “assess the needs and opportunities to develop a space-based operational land imaging capability. In particular, the committee will examine the elements of a sustained space-based Land Imaging Program with a focus on the Department of Interior’s U.S. Geological Survey role in such a program.”   USGS operates the Landsat 5 and Landsat 7 spacecraft that were built by NASA and will operate the next in the series — the Landsat Data Continuity Mission (LDCM, also called Landsat 8).   The Obama Administration proposed in the FY2012 budget request that USGS take over responsibility for the entire Landsat program, including defining the requirements and paying for the spacecraft to be built and launched, roles that NASA currently plays.  Congress did not agree with that plan, however, and the question remains as to how the Landsat program will continue after Landsat 8 is launched.   Scientists are anxious to obtain long term data sets of comparable information and want the Landsat series to continue.  The first Landsat was launched in 1972; the two currently in orbit are well past their design lifetimes and each has partially failed.   This study will be conducted under the auspices of the SSB.  The provisional membership of this study committee has not yet been posted on the NRC’s website.

The NRC is required to post the provisional memberships of its study committees for a 20-day public comment period prior to when a study begins in accordance with section 15 of the Federal Advisory Committee Act (FACA).   Membership on NRC study committees remains provisional until the NRC determines that individuals do not have improper biases or conflicts of interest with regard to the topic of the study.

Events of Interest: Week of January 8-13, 2012

The following events may be of interest in the week ahead.   The House and Senate are meeting in non-legislative pro forma sessions every three days (this tactic has been used in the past to prevent Presidents from making “recess appointments” while Congress is in recess, but President Obama has decided to challenge that interpretation of what constitutes a recess and made several recess appointments nonetheless).  The House returns for legislative business on January 17; the Senate on January 23.

GRAIL Twins Enter Lunar Orbit — UPDATE

GRAIL Twins Enter Lunar Orbit — UPDATE

UPDATE: The two spacecraft entered lunar orbit as scheduled.

ORIGINAL STORY:  NASA’s twin GRAIL spacecraft will enter lunar orbit today and tomorrow, respectively.  The two identical spacecraft  — one following the other as they orbit the Moon — will map its gravity field and give scientists a better understanding of the Moon’s interior.

After decades of study, scientists still do not understand the origin of the Moon.   A new theory is that the Earth originally had two moons that “bumped” into each other, forming the Moon we have today.   The theory responds to observations of the near- and far-sides of the Moon, which are very different from each other.    Observations from GRAIL could help determine if the theory is correct.

The two spacecraft are currently dubbed GRAIL-A and GRAIL-B, but will receive new names once they enter orbit.   GRAIL-A is due to conduct its lunar orbit insertion burn beginning at 4:21 pm EST today, New Year’s Eve.  GRAIL-B will follow suit tomorrow, New Year’s Day, beginning at 5:05 pm EST.

Maria Zuber of MIT is the principal investigator on the GRAIL mission.

Russia's Soyuz Scores Success with Globalstar

Russia's Soyuz Scores Success with Globalstar

Today brought good news for the Russian space program after a series of launch failures over the past 12 months raised concerns about the state of the Russian aerospace industry.  A Soyuz rocket successfully placed six second-generation Globalstar satellites into orbit, just days after a similar Soyuz rocket failed to launch a Russian Meridian communications satellite.

The Soyuz 2.1a used for Globalstar is very similar to the Soyuz 2.1b used for Meridian on December 23.   The cause of the Soyuz 2.1b failure is still being investigated, but initial reports indicate a problem with the third-stage.  Debris from the rocket and satellite rained down over populated areas of northern Russia.    Meridian satelites are successors to the military Molniya series of communications satellites placed into highly elliptical orbit for decades.

The Globalstar launch today was conducted on a commercial basis through Starsem, a Russian-European joint venture that includes the France Arianespace launch services company.   Today’s rocket is similar to the type of Soyuz rocket that is launched from Arianespace’s launch facility in Kourou, French Guiana.    Soyuz is the workhorse of the Russian launch vehicle program and exists in several versions, including one that is used to launch crews to the International Space Station (ISS).  The failure of yet another version of Soyuz in August that was supposed to send a cargo spacecraft to the ISS caused a delay in launching ISS crews.  Whether the December 23 Soyuz launch failure will affect ISS operations remains unclear.

Russia Appoints Deputy Prime Minister to Lead Space Sector

Russia Appoints Deputy Prime Minister to Lead Space Sector

Russia’s news agency ITAR-TASS revealed today that on Monday Russian Prime Minister Vladimir Putin “empowered” Deputy Prime Minister Dmitry Rogozin “to be in charge of Russia’s space sector.”

Rogozin wants a report on Thursday from Russia’s space agency, Roscosmos, on the most recent launch failure, according to ITAR-TASS.  A Soyuz rocket failed to place a military Meridian communications satellite into orbit on December 23.  Today, the launch of a Proton rocket was delayed and the rocket rolled back from the launch pad because of an unspecified technical problem.

In apparent reference to Putin, ITAR-TASS stated:  “According to the head of government, after military acceptance inspection was cancelled many things have changed for the worse. ‘It does not mean we must get back to the former regulation instruments but its [sic] is absolutely obvious that the existing instruments are not enough,’ he added.”   Putin is Russia’s former president, current prime minister, and candidate to become president again next year.   Dmitry Medvedev is Russia’s president.

Russia has experienced an unusual string of launch failures — six in the last 12 months, of which five were in 2011. 

 

 

Congress Finishes Work for 2011

Congress Finishes Work for 2011

The House and Senate passed the two-month extension of the payroll tax cut and unemployment benefits quickly today, completing Congress’s work for 2011.  The bill also keeps Medicare reimbursements to doctors at the current rate instead of declining as they would have otherwise.  No offsetting cuts to NASA or NOAA were included.

The final week was chock full of political drama as House Republicans tried to force the Senate to negotiate a one-year extension before December 31, a route the Senate rejected for the short-term knowing that such negotiations will be complicated and time consuming.  Offsetting cuts will need to be found.  House Republicans did succeed in forcing Senate Democrats and the President to accept a requirement that the President agree to grant a permit for construction of the controversial Keystone XL pipeline from Canada to the Gulf Coast within 60 days of the law’s enactment (today) unless he determines that such a permit is not in the national interest.

The agreement that passed Congress today and was immediately signed into law by President Obama does not affect funding for NASA or NOAA.   Last weekend the Senate rejected a House-passed resolution that would have imposed a 1.83 percent across-the-board rescission of FY2012 funding for those and many other government agencies, although the Department of Defense would have been exempted.

House and Senate negotiators are expected to begin work shortly after the New Year to find a way to extend the payroll tax cut and other provisions for the rest of 2012.   Where the offsetting cuts will come from is anyone’s guess at this point, so no federal agency can rest easy yet.

Soyuz TMA-03M Docks, Hatches Open

Soyuz TMA-03M Docks, Hatches Open

Russia may have suffered another launch failure today, but on a better news front, the Soyuz TMA-03M spacecraft successfully docked with the International Space Station (ISS).

The three Soyuz TMA-03M crew joined the three current residents of the ISS, restoring the space station to its full complement of six.  Soyuz TMA-03M docked at 10:19 am EST and the hatches between the Soyuz and the ISS opened at 12:43 pm EST. The six crew members include three Russians, two Americans, and one European.  To keep up with who’s on board the ISS and what they are doing, visit NASA’s ISS website.

Russia has a launch vehicle named Soyuz (Union), and a spacecraft named Soyuz, which can be confusing.   The Soyuz spacecraft is launched by a Soyuz launch vehicle, adding to the confusion.   The Soyuz TMA-03M spacecraft was launched by a Soyuz-FG launch vehicle.   It is somewhat different than the Soyuz-2 that failed today and somewhat different than the Soyuz-U that failed in August.   However, because of the similarities among the vehicles, following the August failure Russia delayed further launches of the Soyuz-FG until they were certain that the Soyuz-FG was safe to fly.  It is too early to know if today’s launch failure will affect future crew launches to the ISS.

New ISS Crew Set to Dock Friday Morning

New ISS Crew Set to Dock Friday Morning

The three crew currently aboard the International Space Station (ISS) will get an early Christmas present Friday morning — three more crew members, restoring the space laboratory to its full complement of six.

NASA’s Don Pettit, Russia’s Oleg Kononenko, and Europe’s Andre Kuipers (from the Netherlands) are scheduled to dock with the ISS about 10:22 am EST.   They will join NASA’s Dan Burbank and Russia’s Anton Shkaplerov and Anatoly Ivinishin, who boarded the ISS last month.

Burbank got another special treat yesterday, witnessing a comet streak by in the sky.   He took stunning video of it — and of the ISS becoming illuminated at orbital sunrise — that is available on NASA’s website.

Soyuz TMA-03M Launches

Soyuz TMA-03M Launches

UPDATE:   On-time launch at 8:16 am EST.

ORIGINAL STORY:  The launch of Soyuz TMA-03M continues on schedule for launch at 8:16 am EST (7:16 pm local time in Kazakhstan).

NASA and the European Space Agency (ESA) are providing live coverage of the launch.   The three astronauts aboard the spacecraft are NASA’s Don Pettit, ESA’s Andre Kuipers, and Russia’s Oleg Kononenko.

If all goes according to plan, they will dock with the ISS in two days (December 23) at 10:22 am EST. 

Latest Exoplanets Earth-Sized, But Not "Just Right"

Latest Exoplanets Earth-Sized, But Not "Just Right"

The latest findings from NASA’s Kepler space telescope confirm rocky planets the same size as Earth orbiting a star like our Sun, but they are too close to their Sun to be able to support life as we know it.

NASA announced the most recent Kepler findings today.  The planets, designated Kepler-20e and Kepler-20f, are part of a five-planet system orbiting a star similar to our Sun in the constellation Lyra, about 1,000 light years away.

Earlier this month, NASA said that it had confirmed the existence of an Earth-sized planet around a different star that is 600 light years away.  That planet, Kepler-22b, is at the correct distance from its Sun — in the “habitable” or “Goldilocks” zone where the temperature is not too hot, not too cold, but just right — for liquid water to exist. According to current knowledge, life as we know it requires liquid water.

However, NASA said today that Kepler-22b is “likely to be too large to have a rocky surface.”    The two planets discussed today are likely to be rocky, but probably do not have liquid water, NASA said.  The search for Earth-sized, rocky planets in the habitable zone of a star like our Sun continues.

Kepler can not actually see other planets.   It collects data on the dimming of stars that suggests that other bodies — planets — are crossing (“transiting”) between the star and the telescope at regular intervals and thus are in orbit around the star.
