NASA’s Webb Space Telescope to Inspect Atmospheres of Gas Giant Exoplanets

This is an artist’s impression of the Jupiter-size extrasolar planet, HD 189733b, being eclipsed by its parent star. Astronomers using the Hubble Space Telescope have measured carbon dioxide and carbon monoxide in the planet’s atmosphere. The planet is a “hot Jupiter,” which is so close to its star that it completes an orbit in only 2.2 days. The planet is too hot for life as we know it. But under the right conditions, on a more Earth-like world, carbon dioxide can indicate the presence of extraterrestrial life. This observation demonstrates that chemical biotracers can be detected by space telescope observations.[Credits: ESA, NASA, M. Kornmesser (ESA/Hubble), and STScI]
GREENBELT, Md. (NASA PR) — In April 2018, NASA launched the Transiting Exoplanet Survey Satellite (TESS). Its main goal is to locate Earth-sized planets and larger “super-Earths” orbiting nearby stars for further study.  One of the most powerful tools that will examine the atmospheres of some planets that TESS discovers will be NASA’s James Webb Space Telescope. Since observing small exoplanets with thin atmospheres like Earth will be challenging for Webb, astronomers will target easier, gas giant exoplanets first.

KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA’s next planet-hunting mission has arrived in Florida to begin preparations for launch. The Transiting Exoplanet Survey Satellite (TESS) is scheduled to launch on a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station nearby NASA’s Kennedy Space Center in Florida no earlier than April 16, pending range approval.

Mikulski Decides 40 Years in Congress is Enough

Maryland Sen. Barbara Mikulski announced on Monday that she would not be seeking a sixth term next year, bringing a 40-year Congressional career to an end and depriving NASA of one of its most powerful supporters.

Mikulski, 78, said she would rather spend the next two years working on behalf of her constituents rather than raising money and running for re-election. She has served in the Senate since 1987 following a 10-year stint representing Maryland’s 3rd District in the U.S. House of Representatives.

Mikulski is the ranking Democratic member of the Senate Appropriations Committee and the committee’s Commerce, Justice, and Science (CJS) subcommittee, which oversees NASA’s budget. She headed the Appropriations Committee from December 2012 until January 2015.
