WFIRST astronomy mission faces cuts to contain rising costs

November 3, 2017 Stephen Clark

NASA has directed the team developing the Wide-Field Infrared Survey Telescope, a flagship astronomy mission set for launch in the mid-2020s to study dark energy and exoplanets, to reduce the observatory’s scientific capabilities and keep it under a $3.2 billion cost cap.

NASA might privatize one of its great observatories

July 22, 2017 Stephen Clark

Management of NASA’s Spitzer Space Telescope could be turned over to an academic institution or private operator in 2019 once the space agency’s funding for the observatory runs out, a senior NASA manager said this week.

Study teams comb through NASA’s wish list for new telescope

July 21, 2017 Stephen Clark

Scientists outlining four concepts for a powerful new space telescope that could launch in the 2030s this week said improvements in optics, detectors and access to huge new rockets like NASA’s Space Launch System could revolutionize the way astronomers observe potentially habitable planets, black holes, and the earliest galaxies in the universe.

James Webb Space Telescope shipped to Texas for its biggest test yet

May 9, 2017 Stephen Clark

The centerpiece of the James Webb Space Telescope has arrived at NASA’s Johnson Space Center in Houston for a three-month test to ensure the observatory’s sensors and gold-coated mirrors work in the frigid temperatures of deep space.

With an eye on growing cost, NASA aims for 2025 launch of next ‘great observatory’

April 19, 2017 Stephen Clark

NASA managers say the WFIRST mission, the next in the agency’s line of powerful observatories after the Hubble and James Webb telescopes, could cost around $3.2 billion after budgeting for a novel first-of-its-kind instrument to probe the make-up of planets around nearby stars and a bigger-than-expected launch vehicle.

Italian radar satellite, European exoplanet telescope to launch on Soyuz next year

April 7, 2017 Stephen Clark

The Italian government has decided to launch two next-generation radar reconnaissance satellites on Soyuz and Vega rockets from French Guiana, and a European Space Agency telescope to study the structures of planets around other stars will likely ride to orbit as a co-passenger on one of the missions.

Watch a video replay of NASA’s exoplanet announcement

February 22, 2017 Stephen Clark

NASA announced Wednesday the discovery of seven Earth-sized planets orbiting a star 39 light-years from Earth, and three of the rocky worlds may have the right conditions to support life.

Star found with record seven Earth-size planets

February 22, 2017 William Harwood

Astronomers have discovered seven roughly Earth-size planets very close to a cool dwarf star some 39 light years from Earth, including three orbiting in the star’s habitable zone where liquid water, a key ingredient for life as it’s known on Earth, could be present, researchers announced Wednesday.

Potentially-habitable planet discovered around nearest star Proxima Centauri

August 24, 2016 Keith Cooper

A planet with at least 1.3 times the mass of Earth has been discovered orbiting within the habitable zone of the nearest star to our Sun, Proxima Centauri, which is just 4.2 light years away.

Kepler adds 1,284 exoplanets to its total

May 10, 2016 William Harwood

A statistical analysis of data collected by NASA’s planet-hunting Kepler space telescope during its initial mission shows a better than 99 percent chance that 1,284 worlds previously classified as “candidates” are, in fact, actual planets, researchers said Tuesday.
