Cape Canaveral, Oct 16 (AP/UNB) — One of NASA's space telescopes is back in business after a two-day shutdown.
NASA said Monday that the Chandra X-ray Observatory came back online Friday. Chandra's trouble occurred less than a week after the Hubble Space Telescope was sidelined. In both cases, the problem was in the pointing system.
Officials say a glitch in one of Chandra's gyroscopes generated three seconds of bad computer data last Wednesday. That was enough for the 19-year-old telescope to go into so-called safe mode, during which science observations cease. Flight controllers restored Chandra's pointing by switching to a backup gyroscope.
Observations are expected to resume with Chandra by the end of this week. Hubble, meanwhile, remains out of action with a more serious gyroscope issue that cropped up Oct. 5.
Baikonur, Oct 11 (AP/UNB) — Two astronauts from the U.S. and Russia are making an emergency landing after a Russian booster rocket carrying them into orbit to the International Space Station has failed after launch.
NASA astronaut Nick Hague and Roscosmos' Alexei Ovchinin lifted off as scheduled at 2:40 p.m. (0840 GMT; 4:40 a.m. EDT) Thursday from the Russia-leased Baikonur cosmodrome in Kazakhstan atop a Soyuz booster rocket.
They were to dock at the orbiting outpost six hours later, but the booster suffered a failure minutes after the launch.
Russian and U.S. space officials said that the crew is heading for an emergency landing in Kazakhstan at an unspecified time. Search and rescue crews are getting ready to reach the expected landing site.
Vandenberg Air Force Base, Oct 8 (AP/UNB) — A SpaceX Falcon 9 rocket carried an Argentinian Earth-observation satellite into space Sunday and for the first time landed a first-stage booster back at its California launch site.
The primary purpose of the mission was to place the SAOCOM 1A satellite into orbit, but SpaceX also wanted to expand its recovery of first stages to its launch site at Vandenberg Air Force Base, about 130 miles (209 kilometers) northwest of Los Angeles.
SpaceX had previously flown first-stage rockets back to land after Florida launches but had not done so on the West Coast.
The Air Force last week advised residents on the central California coast they might see multiple engine burns by the first stage and hear one or more sonic booms as it returned.
SpaceX also has successfully landed Falcon 9 first stages on so-called drone ships off the coasts of Florida and California, all as part of its effort to decrease the cost of space launches by reusing rockets rather than allowing them to fall into the ocean.
The satellite is the first of two for Argentina's space agency, Comision Nacional de Actividades Espaciales, and will work in conjunction with a constellation of Italian space agency satellites. Its name is short for Satelite Argentino de Observacion Con Microondas.
SAOCOM 1A carries a high-resolution instrument called a synthetic aperature radar that will be used for emergency management during disasters and for land monitoring. The second satellite will be SAOCOM 1B.
Stockholm, Oct 3 (AP/UNB) — The Nobel Prize in chemistry has been awarded to two researchers in the United States and one in Britain.
Half of the 9-million-kronor ($1.01 million) prize was designated for Frances Arnold of Caltech in Pasadena for work that has led to the development of new biofuels and pharmaceuticals.
The other half of the prize will be shared by George Smith of the University of Missouri and Gregory Winter of the MRC Laboratory in Cambridge. They were honored for "phage display of peptides and antibodies."
Paris, Oct 2 (AP/UNB) — All-electric vehicles with zero emissions are among the stars of the Paris Motor Show — rubbing shoulders with the fossil-fuel burning SUVs that many car buyers love.
Volkswagen's Audi and Daimler AG's Mercedes-Benz both on Tuesday showed off battery-powered SUVs for affluent customers.
Mercedes also had a new, bigger version of its conventionally powered GLE sport-utility, while BMW offers a new version of its X-5 SUV that has been a pillar of sales and earnings.
The model mix at the show underlined the contradictions pulling at the industry. The European Union and China are pushing for more electric and hybrid vehicles to reduce greenhouse gases and pollution, while consumers like SUVs and remain reluctant to buy electrics due to cost and range limitations.
