Kepler goes into safe mode as fuel runs low
Posted: Sun, Jul 8 9:43 AM ET (1343 GMT)
Kepler spacecraft illustration (NASA/Ames) NASA's Kepler spacecraft has paused science observations upon receiving indications that the spacecraft may be finally running out of fuel after more than nine years of operations. The agency said Friday that it placed Kepler into a "no-fuel-use" safe mode four days earlier after detecting an anomalous drop in pressure in the spacecraft's hydrazine thrusters. Those thrusters are used to point the spacecraft after the failure of two of its four reaction control wheels earlier in the mission. Kepler will remain in this safe mode until August 2, when it will downlink data it collected during its latest campaign. Mission managers will then decide if the spacecraft can continue operations.

Inmarsat rejets EcoStar takeover bid
Posted: Sun, Jul 8 9:42 AM ET (1342 GMT)
Inmarsat has rejected a second takeover proposal from EchoStar hours before a deadline Friday. EchoStar proposed a deal that valued Inmarsat's equity at $3.2 billion, or $4.2 billion when including convertible bonds. Inmarsat said the proposal "very significantly undervalued" the company. EchoStar is now required to wait six months under British regulations before making another bid. Eutelsat had also shown an interest in Inmarsat last month, but decided at the time not to pursue a bid.
