Introduction

In Episode 142 of This Week in Space, titled “2025 in Space”, hosts Brad Pyle and Tariq Malik delve into the exciting developments and upcoming missions slated for the year 2025. Covering a broad spectrum of spaceflight activities, the episode highlights significant milestones in solar exploration, rocket advancements, planetary missions, and international space endeavors.

1. Parker Solar Probe's Historic Flyby

The episode kicks off with a discussion on NASA's Parker Solar Probe achieving unprecedented proximity to the Sun. During its 22nd flyby, the probe approached within 3.8 million miles of the Sun, reaching speeds of 430,000 miles per hour.

• Brad Pyle [04:30]: “...the Parker Solar Probe made the closest ever and fastest flyby of the Sun...”
• Tariq Malik [04:51]: “And hottest.”

Despite the extreme conditions, the probe's advanced heat shield protected its instruments, maintaining them at room temperature. After initiating an automated approach, the probe successfully transmitted its status back to mission control on December 27, 2024, signaling a "smashing success" and paving the way for further data analysis expected by the end of January 2025.

2. Blue Origin's New Glenn Rocket Milestones

Blue Origin's New Glenn rocket is another focal point, with the company securing an FAA launch license. Recent successful hot tests of all seven first-stage engines mark significant progress.

• Brad Pyle [09:57]: “They named it Jacqueline, after Jeff Bezos's mom.”
• Tariq Malik [09:52]: “Blue Origin got an FAA launch license for their first New Glenn rocket.”

Scheduled launch windows open from January 6th to January 12th, 2025. This development positions Blue Origin as a formidable competitor to SpaceX, with ambitions to handle national security payloads and build a robust launch cadence akin to SpaceX's operations.

3. SpaceX’s Starship Developments

SpaceX continues to push the envelope with its Starship program. The company holds an FAA license for up to 25 Starship launches in 2025, contingent on maintaining consistent mission profiles.

• Brad Pyle [20:26]: “SpaceX has an FAA launch license to fly maybe 25 Starship launches.”
• Tariq Malik [21:31]: “They’re going to catch the upper stage with the second pad.”

Upcoming Flight 7 of Starship is in the pipeline, expected to deploy a payload of simulated satellites mimicking Starlink’s constellation. This flight aims to test new avionics, flight computers, and a reinforced heat shield, enhancing the vehicle’s reusability and operational longevity.

4. Mars Sample Return Mission Challenges

The Mars Sample Return mission faces significant hurdles, primarily due to escalating costs estimated between $6.5 billion and $11 billion. NASA is evaluating whether to continue pursuing this ambitious endeavor or defer to emerging international competitors like China, who aim to achieve a sample return by 2027.

• Tariq Malik [41:32]: “China’s sample was better than that, but NASA's multi-stage plans are incredibly complicated.”
• Brad Pyle [39:40]: “Private industry hasn’t stepped up to save this mission.”

The decision is imminent, with NASA expected to release an updated plan before the end of January 2025, amidst concerns over budget overruns and strategic alignment with broader space exploration goals.

5. NASA's New Administrator Nomination

Anticipation builds around the nomination of Jared Isaacman as NASA's new administrator. Known for his charitable endeavors and entrepreneurial spirit, Isaacman is expected to bring a fresh perspective to NASA, potentially accelerating mission timelines and fostering closer collaboration with private enterprises like SpaceX.

• Tariq Malik [28:35]: “Jared Isaacman is the earliest suggested nominee we’ve ever seen in modern times.”
• Brad Pyle [29:21]: “Jared is incredibly charitable and great with kids—a true space enthusiast.”

Isaacman's confirmation is likely before June 2025, subject to congressional approval, and may signal a strategic shift towards more efficient and commercially integrated space missions.

6. Rocket Lab's Venus Life Finder Mission

Rocket Lab is set to launch its Venus Life Finder mission, targeting the exploration of Venus’s atmosphere for organic molecules essential for life.

• Brad Pyle [68:04]: “Venus Life Finder will drop a probe into the Venus atmosphere to scan for organic molecules.”
• Tariq Malik [63:46]: “If you can float in the upper cloud layer, you can hang out there.”

This mission, leveraging Rocket Lab's Photon vehicle, represents a significant step in interplanetary research, aiming to shed light on the potential habitability of Venus through atmospheric analysis.

7. Vast's Haven One Space Station Initiative

Emerging private company Vast is pioneering the development of the Haven One space station, poised to serve as a successor to the International Space Station (ISS).

• Tariq Malik [51:06]: “Vast is pouring vast amounts of capital into building their Haven One space station without NASA contracts.”
• Brad Pyle [51:53]: “Haven One is fully modular and can be attached to other space infrastructure.”

Haven One is designed to be a flexible, modular platform capable of supporting various missions and partnerships, potentially becoming the primary hub for international and commercial space activities post-2030.

8. China's Tianwen 2 Asteroid Sample Return Mission

China's Tianwen 2 mission stands out with its ambitious plan to collect samples from a near-Earth asteroid and return them to Earth by 2027.

• Brad Pyle [65:57]: “Tianwen 2 will launch to a near-Earth asteroid, collect samples, and return them to Earth.”
• Tariq Malik [65:57]: “They’re targeting asteroid 3200 Phaethon, the source of the Geminid meteor shower.”

This mission not only demonstrates China's growing prowess in deep space exploration but also sets a competitive benchmark for other nations and agencies pursuing similar objectives.

9. European Space Agency’s Space Rider

The European Space Agency (ESA) is advancing its Space Rider, a reusable space transportation system designed for autonomous robotic laboratories and payload deployment.

• Brad Pyle [63:43]: “Space Rider is a reusable space transportation system, similar to Dream Chaser but without foldable wings.”
• Tariq Malik [64:45]: “It resembles the X37B but is fully robotic and utilizes a parafoil for reentry.”

Space Rider aims to facilitate a variety of missions, including satellite deployment and in-orbit experiments, enhancing ESA's capabilities in sustained low Earth orbit operations.

10. Space Force Updates

The U.S. Space Force continues to ramp up activities, overseeing increased launch frequencies from facilities like Cape Canaveral and Vandenberg.

• Brad Pyle [58:10]: “Cape Canaveral Space Force Station has been more active than ever, expecting a much busier 2025.”
• Tariq Malik [57:06]: “Space Force turned five last year...”

With ongoing discussions about budget allocations and potential relocations of Space Command, the Space Force is poised to play a pivotal role in securing and managing U.S. space assets amidst evolving geopolitical dynamics.

11. Rose Parade’s Mars-Related Floats

Adding a cultural twist, the Rose Parade featured floats inspired by Mars missions, including representations of the Perseverance Rover and the Ingenuity helicopter.

• Tariq Malik [16:47]: “The float for Perseverance includes an astronaut riding it, looking ready to fall off.”
• Brad Pyle [16:53]: “There were two space floats this year, which is really cool.”

These creative displays celebrate humanity's achievements in space exploration, blending scientific progress with artistic expression.
