The SpaceX-29 commercial resupply spacecraft will deliver numerous physical sciences and space biology experiments, along with other cargo, to the International Space Station. The research aboard this resupply services mission will help researchers learn how humans, and the plants needed to sustain them, can thrive in deep space.

The biological and physical sciences investigations headed to the Space Station are:

Plant Water Management-5 and 6 (PWM-5 and 6)

NASA has grown plants on the Space Station even without the help of gravity. But microgravity does present challenges and affects Space Station plants' ability to receive adequate hydration and nutrition. The Plant Water Management-5 and 6 (PWM-5 and 6) investigation uses the physical properties of fluids, such as surface tension and wetting, as a mechanism to provide hydration and aeration for plants. Results could advance understanding of the physical aspects of fluid flow and inform designs of fluid delivery systems for reduced gravity environments.

ESA's Hera asteroid mission has completed acoustic testing, confirming the spacecraft can withstand the sound of its own lift-off into orbit. Testing took place within the Agency's Large European Acoustic Facility at the ESTEC Test Center in the Netherlands. This is Europe's largest and most powerful sound system, fitted with a quartet of noise horns that can generate more than 154 decibels of extreme noise.

Diego Escorial Olmos, Hera system engineer comments, "Launch will be the single most stressful day of Hera's life, so we have worked hard to simulate it during our mechanical test phase, first by vibrating the spacecraft on the ESTEC Test Center's shaker tables, and now by blasting it with a noise profile sourced from our launch provider, to be as true to life as possible."

The LEAF chamber stands 11 m wide by 9 m deep and 16.4 m high. One of its walls is embedded with a set of enormous sound horns. Nitrogen shot through the horns can produce a range of noise up to more than 154 decibels, like standing close to multiple jets taking off at once.

Blue Origin has staked out its space at Port Canaveral, right next to SpaceX, with a tower crane for eventual rocket booster recovery operations. Now the company just needs to launch one to put it to work.

The crane arrived at the port as cargo from Germany in October adding another puzzle piece to Jeff Bezos' plans to send up its heavy-lift New Glenn rocket from Cape Canaveral Space Force Station's Launch Complex 36.

"It's now the highest point in our Port Canaveral as a whole," said Port Canaveral CEO Capt. John Murray at a port authority meeting last month. "It's a very, very tall crane and when you look across and you see our mobile harbor crane, it looks very small compared to this Blue Origin crane."

At 375 feet tall, it towers over the port's 302-foot-tall crane, both of which are installed at North Cargo Berth 6.

"That's our crane and a significant milestone as we make rapid progress in New Glenn's development," according to an emailed statement from Blue Origin. "The crane will be used to offload New Glenn's fully reusable first stage from our sea-based landing platform back onto shore in Port Canaveral.
