Israeli spacecraft gets final element before 2019 moon launch

By Ari Rabinovitch

YEHUD, Israel (Reuters) – Israeli engineers on Monday added the final element to a spacecraft destined for the moon – a digital time capsule – and said they aimed to land the craft early next year, somewhere between the landing sites of Apollo 15 and 17.

It will be the first mission of its kind since 2013 and, if it is successful, Israel will be the fourth country to carry out a controlled “soft” landing of an unmanned vessel on the moon.

Since 1966, the United States and the former Soviet Union have put around a dozen of them on the moon and China last did so in 2013.

“The spacecraft is completely built, tested … and will be ready to ship to Cape Canaveral in a few weeks,” said Ido Anteby, CEO of the SpaceIL non-profit that has led the project.

Israel has launched satellites before, but this is the first longer-range Israeli spacecraft of its kind.

The craft, called Beresheet, Hebrew for Genesis, is shaped like a roundtable with four carbon-fiber legs, stands about 1.5 meters tall and weighs 585 kg (1,290 lb) – with fuel accounting for two-thirds of that weight.

It will blast off from Florida on a SpaceX Falcon 9 rocket in the next few months after an initial December date was pushed back.

The time capsule is a single, space-resilient disc, roughly the size of a CD, holding digital files of children’s drawings, photographs and information on Israeli culture and the history of humanity.

“The capsule will remain on the moon and stay in the environment of the moon and maybe in a couple tens of years someone will send a spacecraft to bring it back,” Anteby said.

Beresheet is also carrying a device to measure the moon’s magnetic fields.

SpaceIL is backed mainly by private donors, including U.S. casino magnate Sheldon Adelson and billionaire Morris Kahn who co-founded Amdocs, one of Israel’s biggest high-tech companies.

SpaceIL was founded in 2011 by a group of engineers with a budget of about $95 million. State-owned defense contractor Israel Aerospace Industries has collaborated in the project.

At 60,000 km (37,000 miles) above Earth, the spacecraft will split off from the Falcon launch vehicle. It will at first orbit Earth in expanding ellipses and, about two months later, cross into the moon’s orbit. It will then slow and carry out a soft landing which should cause no damage to the craft.

“Our landing site is located somewhere between the landing sites of Apollo 15 and Apollo 17,” Anteby said. “It’s a flat area. But still, it has small craters and a lot of boulders.”

LOS ANGELES (Reuters) – NASA’s first spacecraft built to explore the deep interior of another world streaked toward a landing scheduled for Monday on a vast, barren plain on Mars, carrying instruments to detect planetary heat and seismic rumblings never measured anywhere but Earth.

After sailing 301 million miles (548 million km) on a six-month voyage through deep space, the robotic lander InSight was due to touch down on the dusty, rock-strewn surface of the Red Planet at about 3 p.m. EST (2000 GMT).

If all goes according to plan, InSight will hurtle through the top of the thin Martian atmosphere at 12,000 miles per hour (19,310 kilometers per hour). Slowed by friction, deployment of a giant parachute and retro rockets, InSight will descend 77 miles through pink Martian skies to the surface in 6 1/2 minutes, traveling a mere 5 mph (8 kph) by the time it lands.

The stationary probe, launched in May from California, will then pause for 16 minutes for the dust to settle, literally, around its landing site, before disc-shaped solar panels are unfurled like wings to provide power to the spacecraft.

The mission control team at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles hopes to receive real-time confirmation of the craft’s arrival from data relayed by a pair of miniature satellites that were launched along with InSight and will be flying past Mars.

The JPL controllers also expect to receive a photograph of the probe’s new surroundings on the flat, smooth Martian plain close to the planet’s equator called the Elysium Planitia.

The site is roughly 373 miles (600 km) from the 2012 landing spot of the car-sized Mars rover Curiosity, the last spacecraft sent to the Red Planet by NASA.

The smaller, 880-pound (360 kg) InSight – its name is short for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport – marks the 21st U.S.-launched Mars missions, dating back to the Mariner fly-bys of the 1960s. Nearly two dozen other Mars missions have been sent from other nations.

InSight will spend 24 months – about one Martian year – using seismic monitoring and underground temperature readings to unlock mysteries about how Mars formed and, by extension, the origins of the Earth and other rocky planets of the inner solar system.

While Earth’s tectonics and other forces have erased most evidence of its early history, much of Mars – about one-third the size of Earth – is believed to have remained largely static, creating a geologic time machine for scientists.

InSight’s primary instrument is a French-built seismometer, designed to record the slightest vibrations from “marsquakes” and meteor impacts around the planet. The device, to be placed on the surface by the lander’s robot arm, is so sensitive it can measure a seismic wave just one half the radius of a hydrogen atom.

Scientists expect to see a dozen to 100 marsquakes during the mission, producing data to help them deduce the depth, density and composition of the planet’s core, the rocky mantle surrounding it, and the outermost layer, the crust.

The NASA Viking probes of the mid-1970s were equipped with seismometers, too, but they were bolted to the top of the landers, a design that proved largely ineffective.

Apollo missions to the moon brought seismometers to the lunar surface as well. But InSight is expected to yield the first meaningful data on planetary seismic tremors beyond Earth.

InSight also is fitted with a German-made drill to burrow as much as 16 feet (5 meters) underground, pulling behind it a rope-like thermal probe to measure heat flowing from inside the planet.

Meanwhile, a radio transmitter will send back signals tracking Mars’ subtle rotational wobble to reveal the size of the planet’s core and possibly whether it remains molten.

NASA officials say it will take two to three months for the main instruments to be deployed and put into operation.

YEHUD, Israel (Reuters) – An Israeli non-profit group plans to land an unmanned spacecraft on the moon in February in the first landing of its kind since 2013.

The craft, which is shaped like a round table with four carbon fiber legs, is set to blast off in December from Florida’s Cape Canaveral aboard a SpaceX Falcon 9 rocket, said Ido Anteby, chief executive of the SpaceIL non-profit.

It aims to transmit pictures and videos back to earth over two days after it lands on Feb. 13 as well as measuring magnetic fields.

“Our spacecraft will be the smallest ever to land on the moon,” said Anteby.

Since 1966, the United States and the former Soviet Union have put around 12 unmanned spacecraft on the moon using braking power to perform “soft” landings and China did so in 2013.

SpaceIL was founded in 2011 by a group of engineers with a budget of about $90 million and they had to sacrifice size and operational capabilities for more efficient travel.

The craft, unveiled on Tuesday at state-owned defense contractor Israel Aerospace Industries, stands about 1.5 meters high and weighs 585 kg (1,290 lb). The spacecraft has four carbon fiber legs and fuel takes up two-thirds of its weight.

At 60,000 km (37,000 miles) above Earth the spacecraft will deploy. It will orbit Earth in expanding ellipses and, about two months later, cross into the moon’s orbit. It will then slow and carry out a soft landing causing no damage to the craft.

“The landing is the most complicated part. The spot chosen is relatively flat and the spacecraft has eye contact with Earth for communication,” Anteby said. “From the moment the spacecraft reaches the point that it begins the landing, it will handle it totally autonomously.”

SpaceIL is backed mainly by private donors, including U.S. casino magnate Sheldon Adelson and billionaire Morris Kahn who co-founded Amdocs, one of Israel’s biggest high-tech companies.

NASA’s Juno spacecraft loops into orbit around Jupiter

By Irene Klotz

CAPE CANAVERAL, Fla. (Reuters) – NASA’s Juno spacecraft capped a five-year journey to Jupiter late Monday with a do-or-die engine burn to sling itself into orbit, setting the stage for a 20-month dance around the biggest planet in the solar system to learn how and where it formed.

“We’re there. We’re in orbit. We conquered Jupiter,” lead mission scientist Scott Bolton, with the Southwest Research Institute in San Antonio, told reporters on Tuesday. “Now the fun begins.”

Juno will spend the next three months getting into position to begin studying what lies beneath Jupiter’s thick clouds and mapping the planet’s gargantuan magnetic fields.

Flying in egg-shaped orbits, each one lasting 14 days, Juno also will look for evidence that Jupiter has a dense inner core and measure how much water is in the atmosphere, a key yardstick for figuring out how far away from the sun the gas giant formed.

Jupiter’s origins, in turn, affected the development and position of the rest of the planets, including Earth and its fortuitous location conducive to the evolution of life.

“The question I’ve had my whole life that I’m hoping we get an answer to is ‘How’d we get here?’ That’s really pretty fundamental to me,” Bolton said.

Jupiter orbits five times farther from the sun than Earth, but it may have started out elsewhere and migrated, jostling its smaller sibling planets as it moved.

Jupiter’s immense gravity also diverts many asteroids and comets from potentially catastrophic collisions with Earth and the rest of the inner solar system.

Launched from Florida nearly five years ago, Juno needed to be precisely positioned, ignite its main engine at exactly the right time and keep it firing for 35 minutes to become only the second spacecraft to orbit Jupiter.

If anything had gone even slightly awry, Juno would have sailed helplessly past Jupiter, unable to complete a $1 billion mission.

The risky maneuver began as planned at 11:18 p.m. EDT as Juno soared through the vacuum of space at more than 160,000 mph (257,500 kph).

NASA expects Juno to be in position for its first close-up images of Jupiter on Aug. 27, the same day its science instruments are turned on for a test run.

Only one other spacecraft, Galileo, has ever circled Jupiter, which is itself orbited by 67 known moons. Bolton said Juno is likely to discover even more.

Seven other U.S. space probes have sailed past the gas giant on brief reconnaissance missions before heading elsewhere in the solar system.

The risks to the spacecraft are not over. Juno will fly in highly elliptical orbits that will pass within 3,000 miles (4,800 km) of the tops of Jupiter’s clouds and inside the planet’s powerful radiation belts.

Juno’s computers and sensitive science instruments are housed in a 400-pound (180-kg) titanium vault for protection. But during its 37 orbits around Jupiter, Juno will be exposed to the equivalent of 100 million dental X-rays, said Bill McAlpine, radiation control manager for the mission.

The spacecraft, built by Lockheed Martin, is expected to last for 20 months. On its final orbit, Juno will dive into Jupiter’s atmosphere, where it will be crushed and vaporized.

Like Galileo, which circled Jupiter for eight years before crashing into the planet in 2003, Juno’s demise is designed to prevent any hitchhiking microbes from Earth from inadvertently contaminating Jupiter’s ocean-bearing moon Europa, a target of future study for extraterrestrial life.
