NASA and JAXA approve replacement of failed Japanese X-ray space telescope

10:39 am

NASA and JAXA have agreed to build a replacement for the Japanese Hitomi X-ray space telescope that failed after only a few weeks in orbit in March 2016.

The X-ray Astronomy Recovery Mission, or XARM, could launch as soon as March 2021, filling a potential gap in astronomers’ X-ray vision of the universe, according to the Japan Aerospace Exploration Agency, or JAXA. NASA has agreed to a junior partner in XARM — pronounced “charm” — and supply X-ray telescopes and a spectrometer instrument for the Japanese-led mission, according to Paul Hertz, directory of NASA’s astrophysics division.

ESA unveils dual orbiter mission to Mercury

10:31 am

After twenty years of development, the European Space Agency this week finally unveiled the completed dual orbiters that it hopes to launch on a seven year journey to Mercury in October 2018.

The 4,100-kilogram BepiColombo consists of two orbiters that will launch together — the ESA-managed Mercury Planetary Orbiter (MPO) and the JAXA-owned Mercury Magnetospheric Orbiter (MMO). The two spacecraft will be delivered to the orbit around Mercury stacked on top of each other by the Mercury Transfer Module (MTM). During the seven-year journey, the MMO will be shielded from the sun by the MMO Sunshield and Interface Structure (MOSIF), which will also serve as a mechanical and electrical interface between the two orbiters.

“MPO focuses on the planet, the surface and the interior size,” said Reininghous. “The orbit is a polar one — 480km times approximately 1500km — a little bit elliptical but extremely close to the planet as such with a return period of 2.3 hours. The data return is estimated at 1.5 gigabit per year.”

The MMO will focus on the planetary environment including the planet’s atmosphere, according to Reininghous. “The orbit is also polar but far more elliptical — 590 km times approximately 11,700 km. It has a period of 9.3 hours. The data return is approximately 10 percent of what we expect from the MPO.”

The European orbiter is much larger and more expensive, with Japanese probe budget being about a tenth the cost.

According to ESA, the mission took so long to build because in 2004, after about seven years of development, ESA suddenly realized that its orbiter’s thermal protection was inadequate, and required a complete redesign. To me, this is either outright incompetence (they knew from the start they were going to Mercury) or a clever way to extend the funding so that it provides an entire lifetime’s work for its builders. Think about it. Twenty-one years from concept to launch, then seven years to fly to Mercury, and then one to two years in orbit. That’s more than thirty years for this single mission.

Japan to try another launch of low-cost mini-rocket

10:10 am

The competition heats up: Japan has decided, following a January launch failure, to try another launch attempt in 2017 of a test of low-cost mini-rocket.

Participating businesses will likely bear the brunt of the 300 million yen to 500 million yen ($2.64 million to $4.4 million) launch cost, though the government will likely allocate funds as well. JAXA aims to have the rocket finished by autumn. It will soon plan out how to procure needed parts and build the vehicle in time for a 2017 launch, then submit the plan to the Ministry of Education, Culture, Sports, Science, and Technology. The ministry will secure a launch site accordingly, and a safety and inspections committee of its space division will review the plan.

January’s rocket was a three-stage version of the existing two-stage SS-520, modified to carry a miniature satellite. Off-the-shelf consumer product technology was incorporated to keep costs down. The rocket blasted off successfully. But during the first stage of the launch sequence, transmission of such critical data as its temperature and position ceased. The agency aborted the second stage, letting the vehicle fall into the ocean.

This second attempt, and the speed in which they appear to be gearing up to launch it, suggests that Japan might finally be recognizing that it has been failing badly in its efforts to participate in the new commercial launch market, and needs to energize its launch industry if it wants to participate in the exploration of the solar system.

Japanese SS-520 rocket launch scrubbed due to weather

8:51 pm

The launch of Japan’s new small rocket, SS-520, was scrubbed today due to bad weather.

Japanese officials announced a few minutes before the launch that the flight would be postponed due to bad weather at the space base. Authorities did not immediately set a new launch date.

The SS-520-4 will try to become the smallest rocket to ever put an object in orbit. Its sole payload is the six-pound (three-kilogram) TRICOM 1 spacecraft, a CubeSat from the University of Tokyo designed for communications and Earth observation experiments. Standing 31 feet (9.5 meters) tall and spanning around 20 inches (52 centimeters) in diameter, the SS-520-4 will blast off from a rail launch system and head east over the Pacific Ocean, dropping its lower two stages and payload enclosure into the sea in the first few minutes of the flight.

Primarily funded by a $3.5 million budget provided by the the Japanese government’s Ministry of Economy, Trade and Industry, the SS-520-4 program is a one-off demonstration by Japan’s space agency, which aims to validate low-cost technology and launch operations procedures for a future “nano-launcher” to deploy tiny satellites in orbit on dedicated rides.

The last paragraph is disappointing, but not surprising considering that this rocket is entirely owned and built by the government, which like NASA, routinely builds things and then abandons them, no matter how useful they are. I hope that some private company grabs the design here and runs with it.

JAXA signs agreement with private lunar mining company

9:16 am

The competition heats up: Japan’s space agency JAXA has signed an agreement with ispace inc, a private lunar mining company that is also behind Japan’s only competing team in the Google Lunar X-Prize competition.

It is not clear if what this agreement entails. X-Prize competitors have to announce a contract with a launch company before the end of 2016, and this announcement does not say whether JAXA will provide that service to Japan’s competitor.

Japan developing small rocket for commercial smallsats

8:41 am

The competition heats up: Canon has joined a new project by the Japanese space agency JAXA to develop a small rocket for commercial smallsats.

The three-stage rocket is an upgrade to JAXA’s two-stage SS-520, which carries instruments for research observations. Measuring 52cm in diameter and less than 10 meters in length, the new version will cost less than one-tenth as much to launch as leading rockets and is expected to be used to lift microsatellites in orbit. An initial launch is slated for early next year from the Uchinoura Space Center in Kagoshima Prefecture.

A planetary cubesat mission by Japan

5:16 pm

When Japan launched Hayabusa-2 last week it also sent a secondary payload towards the asteroid, a cubesat designed to test the engineering of using minisats for future planetary missions.

PROCYON, which stands for PRoximate Object Close flYby with Optical Navigation, is a 65-kg (143 lb.) spacecraft designed to demonstrate that micro-satellites can be used for deep-space exploration. In addition to testing out micro-sat systems in deep space, the spacecraft is to conduct a close flyby of an asteroid. Developed by the University of Tokyo and JAXA, PROCYON was launched as a secondary payload along with Hayabusa2 on Dec. 3. JAXA reports that controllers have received confirmation that PROCYON was inserted into its planned interplanetary orbit as scheduled two hours after launch.

The spacecraft, which measures only 630 x 550 x 550 mm (24.8 x 21.65 x 21.65 in), has a mission that is divided into nominal and advanced phases.

If this engineering proves viable, which we have every reason to expect, it will open the door to many more planetary missions, costing far less and requiring much smaller rockets to launch.

    Japan’s unveiled its new Epsilon rocket yesterday, scheduled for its first launch next week.

    9:10 am

    The competition heats up: Japan’s unveiled its new Epsilon rocket yesterday, scheduled for its first launch next week.

    Epsilon is a low-cost, high-performance, solid-fuel rocket co-developed by JAXA and IHI AEROSPACE Co.,Ltd. and designed to launch scientific satellites. Epsilon features the world’s first innovative launch system called “Mobile Launch Control” which allows for built-in checks to be conducted autonomously within the rocket’s system. This allows staff to focus on high-level monitoring, making overall performance very smooth. A spokesman joked that it is so easy to control that staff could monitor the rocket on their laptops while at Starbucks.

    In the past Japan has not been very good at building cheap and efficient rockets. We shall see how this one does.

    Japan’s entire space program faces a major overhaul.

    12:59 am

    Feeling the heat of competition: Japan’s entire space program faces a major overhaul.

    In the last few decades Japan has not done very well in space when compared to other Asian countries like China and India. Thus, this overhaul. Yet, based on this article, it doesn’t seem to me that they are making the real changes they need to do to successfully compete. If anything, it sounds instead like the actions of a bureaucracy that is merely rearranging the deck chairs on a sinking ship, in the hope that this will somehow save it.
