InSight was supposed to launch in March, but a series of leaks in a mission-critical instrument, the Seismic Experiment for Interior Structure (SEIS) provided by the French space agency, CNES, will keep the mission grounded well past a 26-day Mars launch window that opens March 4, Grunsfeld said.

Verizon & Sprint may owe you money
Verizon and Sprint have previously said they stopped the cramming practice long before the government began its investigations. You may be entitled to a refund for unauthorized and previously unrefunded Premium SMS charges incurred since July 1, 2010.
According to ABC News, the cause of the delay is a leak in a science instrument on the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander.
FAA, states spar over regulating drones
In order to register your drone, the owner has to report his personal identity and the objective for which he’d use the sUAS. He also noted that some people use drones to take aerial photography, and the airport is a popular spot for photographers.
“Space exploration is unforgiving, and the bottom line is that we’re not ready to launch in the 2016 window”, Grunsfeld said.
Small Indian paramilitary plane carrying at least 10 crashes
A light aircraft has crashed on take-off near the airport in the Indian capital, Delhi, killing 10 people. The BSF has a small flying division but we ensure that our planes are the best and are not in bad shape.
“Learning about the interior structure of Mars has been a high priority objective for planetary scientists since the Viking era”, says John Grunsfeld, associate administrator for NASA’s Science Mission Directorate.
Engineers won’t be able to fix the problem in time for the lander’s scheduled March 2016 blast-off. The fault discovered was a leak in the vacuum-sealed metal sphere that held three seismometers. If not ultimately cancelled, the InSight mission would be delayed until at least 2018, which would be the next launch opportunity for any craft heading to Mars.
The uncrewed Exploration Mission-1 (EM-1) is the next space flight of Orion that will be launched into a distant retrograde orbit around the moon in 2018.
Perception came a week ago in Florida at Vandenberg Air Force Base to start products in front of a launch.
About $525 million of the mission’s $675 million budget has been spent.
NASA said a decision on how to proceed with the mission will be made in the coming months.
Instead, it’s being sent back to its maker – Lockheed Martin – in Denver. It would have landed on Mars six months after launch.
The InSight mission was to investigate whether the core of Mars is solid or liquid like Earth’s and why Mars’ crust is not divided into tectonic plates that drift like on the Earth.
Built by Lockheed Martin, the unmanned spacecraft was due to land on the red planet and drill deep into its surface to give scientists a better idea of how it was formed.

The seismometer, which measures about eight or nine inches in diameter, is sensitive enough to measure vibrations so slight, they are “at the level of the size of an atom”, Bruce Banerdt, principal investigator of the InSight project at the Jet Propulsion Laboratory. “It’s just a hiccup on our path to getting this kind of science, this kind of understanding of our solar system and our place in the universe”.
