And of course there will be a delay
The main point of the mission was to measure the mass of the object, because
this is how you really measure the deflection," said Michel.With a camera and
miniaturised satellite, the new AIM will have a much reduced payload -- minus a
lander and radars to probe the moon&Vacuum space bag39;s internal
structure.Larger than a bomb But the methods must be tested and refined with
real-life practice runs to prepare for "if we actually have to deflect an
asteroid some day.
Two or three years (after impact), these things won't
change," said Michel.It is about 160 metres (525 feet) wide, the size of an
object that would hit Earth with the equivalent force of 400 megatonnes of TNT,
"more than the largest hydrogen bomb," said Cheng."European Space Agency boss
Jan Woerner told AFP "we will go forward with a new proposal" for the next
ministerial meeting in 2019."There are measurements that AIM can make that DART
cannot," said Cheng."We have never # tested asteroid deflection and there is no
way we can test in (the) laboratory.. But we found something I think that still
works and allows to relax the very tight schedule.
The new price tag? About 210
million euros, said Patrick Michel, the science lead for the European part of
the project."Scientists from both sides of the Atlantic urged European congress
participants to sell the project to their national representatives.In its new
form, AIM could still do these crucial measurements even if NASA sticks to its
own timeline and hits Didymoon in 2022."It is important for humanity, as a
species we have the means today to deflect an asteroid. (Photo: AFP) Space
scientists urged Europe Wednesday to rethink its withdrawal from a futuristic,
international dry-run for an Armageddon-like mission to deflect a space rock on
a calamitous collision course with Earth.He is the project scientist for the
American part of the AIDA mission, named Double Asteroid Redirection Test
(DART), which has entered Phase B -- meaning it has been approved but still
needs final confirmation.
And of course there will be a delay. It's not a
question of if, but when," he said by email..""We have not discovered any
asteroid that is actually coming to Earth," said Cheng, but "we may still
discover one" among the thousands of hazardous space rocks believed to be out
there. that we have the two at the same time.Dubbed AIDA (Asteroid Impact &
Deflection Assessment), the test mission is crucial if we are to develop the
capacity to protect our planet from incoming projectiles, they said.At the
meeting in the Latvian capital, European scientists proposed an altered,
slightly cheaper alternative for AIM. We can do something," stressed
Cheng.Europe's contribution, to send a small craft close to the action to
measure the crash and its impact, suffered a setback when space ministers
rejected a 250-million-euro ($300-million) funding request last December.An
asteroid that exploded in the atmosphere over Siberia in 2013 injured some 1,600
people. We know it will happen, one day sooner or later. We need to know if our
models are correct, (whether) our simulations work as expected.The test mission
is crucial if we are to develop the capacity to protect our planet from incoming
projectiles.Didymos's moon Didymoon, the target of the AIDA mission, falls in an
even more dangerous size range.
The project was called AIM, for Asteroid Impact
Mission."This is the kind of disaster that could be a tremendous catastrophe,"
Andrew Cheng from Johns Hopkins University's Applied Physics Laboratory told AFP
at a European Planetary Science Congress in Riga. An asteroid that exploded in
the atmosphere over Siberia in 2013 injured some 1,600 people."Of course it's
better.Unlike most other natural hazards, an asteroid strike "is something that
the world is able to defend.DART will entail smashing a spacecraft into the tiny
moon of a faraway asteroid dubbed Didymos to alter its trajectory -- a
scientific first."We all together have to convince the national delegations to
spend some money for this mission," added ESA's Michael Kueppers

The lander will essentially be on autopilot, and a computer will be in charge of
firing the various thrusters and steering the lander safely down.Dr Sivan and
his colleagues, however, should wait for the big moment in early September when
"Vikramâ€, the lander, along with the rover "Pragyanâ€, is expected to break off
from the orbiter and gently land on the moon’s surface.
This will be a huge leap
forward for India’s ambitious space programme, and scientists and defence
experts everywhere are watching to see whether the country can pull it off.If
the rest of the mission goes as well, India will become the fourth nation —
after the United States, Russia and China — to land on the moon, more than
384,000 km away. A roaring thunder echoed across the sky after the rocket
blasted off exactly at 2.Amid sustained applause from his colleagues, the team
of scientists and engineers at the space agency, Dr Sivan said: "We fixed that
technical snag now and Isro bounced back with flying colours!â€
He added that the
efforts of rocketry experts paid off with the GSLV Mk-III placing Chandrayaan-2
in a better orbit than was earlier envisaged.An emotional Dr Kailasavadivoo
Sivan, chairman of the Indian Space Research Organisation, thanked his
colleagues for the "beginning of a historic journeyâ€.."The mission has been
successfully accomplished,†announced a scientist at the Mission Control Centre,
16 minutes and 14 seconds after the 142-foot, 700-ton rocket climbed on a plume
of orange flames, before vanishing into a thick bank of clouds over the Satish
Dhawan Space Centre (SDSC), Sriharikota Range. In view of the delay in
communicating across such far distances, the engineers and scientists at mission
control centre will not be able to intervene.

Chandrayaan-2 with the week-long delay in its 50-day journey to the moon proving
a blessing in disguise. The gigantic rocket, GSLV MkIII, propelled the country’s
second lunar probe 6,000 km deeper into space than originally planned on Monday
afternoon. Its target is a region near the moon’s mysterious south pole, where
no other missions have so far explored.

Currently, if an antenna is not perfect, you have to live with it, with the
losses,†said Tamir. That may not sound like much, but those are two major
hurdles that have limited satellite operators for years.â€.The way he hopes to do
it is by using a parachute-like antenna that deploys once in space.
This type
of solution will conquer the market, because it addresses some of the most
serious and bothersome issues for satellite operators,†said David Pollack,
Spacecom’s chief executive.Spacecom, which is collaborating with Facebook to
beam Internet services to Africa, said that if the new Skyfi antenna is
successful, it would be in huge demand.The two technology leaders are working on
ways to beam Internet access from the sky to remote areas, Google with
high-flying balloons and Facebook with a combination of drones and larger, more
complex satellites.
While the company says it has a working "proof of conceptâ€,
the technology has yet to be proven in space, so don’t expect a fleet of
Internet-providing nanosatellites for at least a few years. But it will take an
orbiting cluster of 60 miniature, or nano, satellites, each about the size of a
shoe box, to provide full coverage of earth, said Raz Itzhaki Tamir, a veteran
of Israel’s aerospace industry who co-founded Skyfi four years ago. "We can
change that and be flexible, thus gaining more revenue from the

Skyfi is looking to outflank Facebook and Google in a race to provide worldwide
Internet access by developing the first self-correcting antenna that can turn
mini-satellites into powerful transmitters covering the globe.
For now, Skyfi is
perfecting its system by testing a large version of the antenna in a
50-square-meter (yard) echoless chamber that simulates the conditions of space.
The antenna can then mechanically adjust itself for imperfections in the
transmitter’s surface, allowing a stronger signal to pass, and even alter the
direction it points should broadcast needs change over the course of the
satellite’s life.Thousands of new satellites will be launched into space in the
coming decade and many will use technology from Israel, which has built on its
military expertise to capture a sizeable chunk of the growing commercial space
market, particularly in the field of miniaturisation.
It plans to launch its
first unit in the next 18 months.Skyfi raised $3 million in a round led by
Jerusalem Venture Partners, one of the country’s most successful venture capital
funds, and says it has signed letters of intent to sell its antennas to global
players such as Lockheed Martin and Spacecom. But the antenna alone could be big
business in the meantime
