NASA MISSION UPDATE
NASA’s Stardust-NExT spacecraft is nearing a celestial date with comet Tempel 1 at approximately 8:37 p.m. PST (11:37 p.m. EST), on Feb. 14. The mission will allow scientists for the first time to look for changes on a comet’s surface that occurred following an orbit around the sun.
Some interesting news via the Chinese Xinhua news agency that RSC Energia plans to build a nuclear-power “orbital pod” to clean up space debris. The details include:
- cost: 600 billion rubles ($1.9 billion USD)
- cleanup 600 satellites by dropping them in the ocean over 10 years
- begin operations by 2023
- 15 year lifespan.
The report also indicates that Energia has been developing plans for a “space interceptor designed to destroy dangerous space objects heading toward the Earth.” These presumably would be near Earth objects.
As with many Russian projects, it’s not clear if there is money available or this is a proposal looking for funding.
NASA MISSION UPDATE
The EPOXI mission’s recent encounter with comet Hartley 2 provided the first images clear enough for scientists to link jets of dust and gas with specific surface features. NASA and other scientists have begun to analyze the images.
The EPOXI mission spacecraft revealed a cometary snow storm created by carbon dioxide jets spewing out tons of golf-ball to basketball-sized fluffy ice particles from the peanut-shaped comet’s rocky ends. At the same time, a different process was causing water vapor to escape from the comet’s smooth mid-section. This information sheds new light on the nature of comets and even planets.
During the International Academy of Astronautics Summit on Wednesday, Roscosmos Head Anatoly Perminov laid out Russia’s ambitious plans for Solar System exploration, which includes a sample return from Phobos and the Moon as well as landings on the planet Mercury and Jupiter’s moon Europa. The meeting, which was aimed at deepening international cooperation in space, was attended by 27 heads of space agencies.
The Russian space agency and ITAR-TASS reported on Perminov’s comments, which also included remarks about nuclear propulsion, climate change monitoring, asteroid missions, space situational awareness, and the International Space Station.
Space.com’s Leonard David has a report on a recent meeting in Europe to coordinate an action plan to battle near Earth objects that could rain havoc down on our planet:
Space agencies around the world are working to be ready to coordinate their response to any potentially harmful asteroid headed for Earth.
To help focus a world-class planetary defense against threatening near-Earth objects, the space experts are seeking to establish a high-level Mission Planning and Operations Group, or MPOG for short.
