ISRO released first light images of Mars taken by Mangalyaan’s color camera payload. Time to drool
ISRO scientists recently reawakened the frozen orbiter Mangalyaan or short MoM, from its deep slumber, test firing its main rocket motor for 4 seconds. The risky phase went smoothly and according to ISRO
the craft will reach Mars tomorrow. The sensors aboard the craft are already detecting acceleration in the craft as it is being pulled into Mars’s gravitational well ( or fancily called Mars sphere of influence ) indicating that it is already in the neighborhood of the red planet… as expected 😛
Tomorrow, the probe will autonomously fire its liquid apogee motor (LAM), when the craft is eclipsed by the red planet from our view on earth.
Mangalyaan first perform a back flip to point its main engine against its current velocity vector, i.e. the direction its flying in. It’s speed will drop significantly and get caught in a highly elliptical orbit around Mars ( see ISRO graphic )
If the LAM fails to fire, ISRO is banking on eight smaller engines which may be used alternatively. Commands related to all of these scenarios have been already uploaded into the craft a few days ago. If nothing works, short of a spacecraft exploding in deep space ( just kidding ), the orbiter would just shoot past Mars and the get hurled into a trajectory that would send it out of the solar system.
For now scientists
Stay tuned….as more exciting times are ahead!
So, me and some of my astronomy enthusiast friends went out to look for Aurora borealis here up in Northern Minnesota. As luck would have it we had a hard time dealing with cloud cover and the moon rising at around 9 pm local time . However as i was playing with may camera, trying to detect any signs of an auroral glow, this nice visitor showed up in front of my camera.
The bright meteor left a nice smoky trail as it blazed by. The fireball’s flash was so bright that it could cast shadows on the ground.
|Sunspot 2158 eurupted on Wednesday 10/9 at 1746UTC, hurling an X-Class solar flare right towards us. The flare is scheduled to reach on Friday, A radiation flash from the explosion ionized the upper layers of Earth’s atmosphere, disturbing HF radio communications for more than an hour. More importantly, the explosion hurled a CME directly toward Earth. The Solar and Heliospheric Observatory photographed the expanding cloud|
What to Expect?
HF Communication issues
Pandemonium and chaos… nope kidding about this one 😛
