Space junk in orbit is bad enough, but on Mars?

Considerations about house junk on Mars.

A brand new paper mentioned that particles jettisoned by spacecraft as they land on Mars, similar to parachutes and warmth shields, might complicate future pattern return missions.

These elements might cowl or harm pattern caches that these future missions are meant to retrieve for return to Earth.

The paper advisable that these gadgets be jettisoned throughout touchdown in order that they fall kilometers away to keep away from interfering with the mission. [Seeker]

Ultimate preparations are underway for the launch of a Cygnus cargo spacecraft on an Atlas 5 this morning. The launch of the Cygnus, on a mission designated OA-7, is scheduled for 11:11 a.m.Japanese from Cape Canaveral. No technical points have been reported and climate is forecast to be favorable. The Cygnus is carrying greater than 3,400 kilograms of cargo for the station, and can arrive on the station Saturday assuming an on-time launch at the moment. [CBS]

Orbital ATK might launch future Cygnus missions on Atlas 5 autos relying on NASA’s wants. The corporate’s follow-on cargo contract with NASA provides the company the choice of selecting to launch Cygnus spacecraft on both the Atlas 5 or its personal Antares rocket. Orbital ATK expects to listen to from NASA “quickly” in regards to the mixture of autos it desires to make use of on that contract. Orbital ATK initially deliberate to launch all its Cygnus missions on its present contract on the Antares, however an October 2014 failure led it to make use of the Atlas 5 for 2 missions. It chosen the Atlas 5 for this mission, regardless of having returned the Antares to flight final fall, with the intention to meet NASA wants for extra cargo. [table4]

China rolled out the rocket for its first cargo spacecraft launch Monday. The Lengthy March 7 rocket, carrying the Tianzhou-1 spacecraft, moved to the pad Monday on the Wenchang Satellite tv for pc Launch Middle on the island of Hainan. The launch is scheduled for Thursday. Tianzhou-1 will dock with the Tiangong-2 house laboratory module in orbit, demonstrating the flexibility to refuel the module. China plans to make use of future Tianzhou spacecraft to resupply the house station it’s creating. [Spaceflight Now]

India’s house company is planning to develop a three way partnership with business to provide launch autos. The three way partnership, which might contain as much as half a dozen corporations and lots of extra subcontractors, would construct the Polar Satellite tv for pc Launch Automobiles which have grow to be the workhorse for the Indian house program. The primary PSLV launch by that three way partnership is deliberate for 2020 or 2021. [PTI]

Giant constellations of communications satellites might create a dramatic improve in orbital particles. A brand new research simulating the consequences of recent satellite tv for pc techniques discovered that constellations of hundreds of satellites might lead to a 50 % improve within the variety of collisions between satellites and particles. European officers, holding a convention on house particles this week in Germany, are involved that such techniques might not give a lot thought to methods to mitigate these dangers, similar to deorbiting satellites on the finish of their lives.
