NASA’s Transiting Exoplanet Survey Satellite, built to find planets around other stars that are close enough for detailed follow-ups by future telescopes, launched Wednesday into a unique high-altitude orbit on top of a SpaceX Falcon 9 rocket from Cape Canaveral.

Saturn’s clouds run deep, rings may rain organics

6 April 2018 Stephen Clark

Saturn’s clouds have roots deeper inside the planet’s atmosphere than scientists previously thought, and Saturn’s rings — now believed to have formed in the last 200 million years — appear to be raining organic molecules down on the planet, according to observations made by NASA’s Cassini spacecraft last year in the final weeks of its mission.

Webb telescope’s launch delayed until 2020

Blaming a slew of technical snags and “avoidable errors,” NASA officials said Tuesday that the launch of the James Webb Space Telescope, already years behind schedule, will be delayed to 2020, potentially pushing the mission’s development cost above an $8 billion cap mandated by Congress.

British-led exoplanet mission selected as ESA’s next space science probe

The frozen faraway miniature world targeted for a high-speed flyby by NASA’s New Horizons spacecraft on 1 January 2019, now has a nickname: Ultima Thule.

Exoplanet-hunting satellite arrives in Florida for April launch

18 February 2018 Stephen Clark

NASA’s Transiting Exoplanet Survey Satellite has arrived at the Kennedy Space Center in Florida for final testing, fueling and attachment to a Falcon 9 launcher for liftoff in mid-April, a delay of nearly one month to allow SpaceX additional time to prepare the rocket for the mission.

Organisers confirm no teams will win Google Lunar X Prize

26 January 2018 Stephen Clark

None of the teams who have spent the last decade chasing a $20 million grand prize by placing a privately-funded lander on the Moon will meet a deadline at the end of March to claim the award, the organisers of the Google Lunar X Prize announced Tuesday.

Asteroid missions on track to reach their destinations in 2018

18 January 2018 Stephen Clark

Pioneering spacecraft from NASA and the Japanese space agency promise to reveal two unexplored asteroids later this year, officials said Wednesday, beginning surveys that will culminate in daring descents to capture samples for return to Earth, where eager scientists await a hands-on look at the specimens.

Plot thickens as New Horizons moves within year of next flyby

6 January 2018 Stephen Clark

The final days before NASA’s New Horizons probe barrels in on its next destination on Jan. 1, 2019, should prove eventful, with scientists trying to sort out whether a distant mini-world detected by the Hubble Space Telescope more than three years ago may actually be a swarm of icy objects.

Titan drone, comet sampler picked as finalists for NASA mission

20 December 2017 Stephen Clark

NASA has narrowed its choices for a new billion-dollar robotic space mission: A nuclear-powered quadcopter to explore the hazy landscape of Saturn’s largest moon Titan, or a probe to scoop up a piece of a comet and return it to Earth.
