The US National Aeronautics and Space Administration (NASA) has begun its quest to investigate requirements for preventing a hazardous asteroid from hitting Earth.

The Double Asteroid Redirection Test (DART) mission will be the first demonstration of a kinetic impactor technique to change the motion of an asteroid in space. The DART satellite is designed to impact an asteroid as a test of technology, according to a NASA statement. The collision between the DART satellite and the target asteroid is expected in September 2022.

The asteroid system being targeted by NASA is a testing ground to determine if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future. NASA said while no known asteroid larger than 140 m in size has a significant chance to hit Earth for the next 100 years, only about 40% of those asteroids have been found as of October 2021.

US Coast Guard Airbus MH-65s retire from Arctic mission

The last US Coast Guard (USCG) Airbus MH-65 Dolphin in Alaska retired from Air Station Kodiak on 23 April, ending the type's 36-year employment in the service's Alaska Patrol (ALPAT) role.

“For decades, the cutter and helicopter team were the core of the ALPAT mission,” said Commander James Kenshalo, a USCG MH-65 Dolphin pilot. “Together they projected force and protection to the most extreme remote regions of our nation's territories, operating beyond where help could reach.”

Air Station Kodiak operates six Sikorsky MH-60Ts and is scheduled to receive three more in 2025. The service intends to standardise its full rescue helicopter fleet on the MH-60T, which has a longer range, greater payload capacity, and commonality with other armed service fleets. Alaska is among the first regions to complete the transition because of the long ranges required to perform rescue and security missions in the region.

Italy to enhance SSA with new ground-based sensors

by Olivia Savage

Flyeye is a multiple-optics telescope with a very wide field of view that will be capable of classifying objects in space as small as 15 cm in LEO and 35 cm in MEO. The 6.5 m high and 4 m wide telescope will be used by the Italian Space Agency and military for SSA. (OHB Italia)

The Italian National Armaments Directorate (NAD) is procuring three ground-based sensors to enhance the country's space situational awareness (SSA), Janes learnt at the Military Space Situational Awareness Conference 2024, held in London from 22 to 24 April.

In total, two optical telescopes and one high-performance radar are being procured as part of its national SSA plans, Lieutenant Colonel Ferdinando Dolce, the head of SSA at NAD, said at the conference.

The first sensor being procured is a high-performance optical surveillance telescope from OHB Italia called Flyeye, Lt Col Dolce said.

Flyeye will have the capacity to monitor objects in low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit (GEO), Commander of the Space Situational Awareness Centre at the Italian Air Force Colonel Dario Tarantino told Janes

Bangalore-based GalaxEye Space is developing a satellite that can carry multiple sensors for Earth observation to support the requirements of the Indian Armed Forces.

Speaking to Janes at the Indian DefSpace Symposium 2024 held in Delhi from 18 to 20 April, Deb Jyoti Pal, senior vice-president of business development at GalaxEye said the company is planning to launch the satellite into space in early 2025 for evaluation.

This low Earth observation (LEO) satellite will host an electro-optic (EO) sensor, and a synthetic aperture radar (SAR) with both sensors capturing data simultaneously to provide a more holistic view of strategic areas of interest, Pal added.

“The SAR sensor can capture data in day and night, and in any weather condition including in foggy or cloudy environment. EO sensors are not able to do this. On the other hand, SAR data can be difficult to interpret. This is where EO data can benefit a user,” Pal said.
