It was cool to shake hands with astronaut Ron Garan at the NASA Space Apps Hackathon this weekend! Congrats to NYC SpaceCal and Tiny Sea Bots, who'll be going on to the global competition, as well as all the other honorees:  Droid Hopper, Chillin' On Mars, Versioning Goat, Asteroid Mapper, Star Map Sculpture, WhyWeExplore, Spacerac.es and Le Big Blue.

This Thursday is NY Tech Day (a.k.a. the world's largest startup event). Free mocktails from BuzzTheBar when you walk in! Don't forget the after-parties, like the Big Data bash with Knewton and Get Acquainted with Acquaintable.

This Friday is the Entrepreneurs Roundtable Accelerator (ERA) Demo Day. Good luck to all!

Next week is the Digital Content NewFronts where the likes of Google, Yahoo, Hulu, AOL and others will be showcasing original video content. Also coming up on May 7 is Innovating for the Connected Home, Living Room & TV, hosted by Mashable, Verizon and the MIT Enterprise Forum. It'll focus on ideas for new products and services for today’s high-speed-connected home.

Deadlines: April 30 is the last day to apply for the Co.Labs and Target Retail Accelerator. The winner gets a cool $75,000 and the chance to work with a leading innovator in the retail space, plus seven finalists will get $10,000 each. Applications for Matchpoint East are due April 29. It's an exclusive opportunity for health-tech entrepreneurs to meet large stakeholders like Kaiser, Blue Cross Blue Shield, and Aetna. Yup, that can open doors! Innovate Health is also inviting locals to develop commercially viable technologies for urgent healthcare problems. Deadline is May 2.

Plus, the deadline for the National STEM Video Game Challenge has been extended to May 1. Last but not least, don't forget that the 30 percent early-bird discount (code: 'garysguide') for the Funding The Best In Global Innovation Conference expires May 1.

If you go to lots of conferences and events (like I do), I'd recommend you check out an app called Bizzabo. Its goal is to maximize your networking and help you discover new business opportunities. With TechCrunch Disrupt and Internet Week coming up, this might be just the ticket!  :)

You know what I'm excited about? The CitiBike Share Program, that's what. I think I can see myself riding a CitiBike around town--though maybe wearing my suit and red tie and riding a bike sounds a bit crazy. But hey, this is New York City. Registration for the program is now open. They launch in May so get a jump on it, people!

And finally, today is April 22, so Happy Earth Day, y'all! Hopefully Elon Musk will soon figure out a way to get us to Mars. But until then, remember we only have one planet to live on. So let's take good care of it!

And now let's see what's going down in the Alley this week...

Congrats to the Ravens for winning the Super Bowl! Best of the commercials? That'd be Chrysler's So God Made A Farmer ad. Beyoncé rocked the half-time show (and flashed the Illuminati sign?). Yes, there was a brief blackout, enough to unleash a torrent of funny tweets. Oreos won the night, social-media wise. And finally, there was Shaq, lip-syncing to Beyoncé's "Halo." 

R.I.P., Mayor Koch. You will be missed. New York is the greatest city in the world. But there was a time when the future looked bleak, and Mayor Koch deserves some of the credit for bringing the city back from the brink.

The NYC EDC is planning the 4th Annual BigApps competition. Help them out by completing this brief survey by Friday. Also, wanna help the city reinvent the payphone? Submit your prototype idea by February 18. Demo Day is March 5.

Some suggestions, like Robert L.'s idea for a visualization app "that allows me to 'see down through the streets' down to the subway below our feet" sounds awesome, if implausible to create. But what's with all the G-rated suggestions? No one wants an app that hacks ATMs to spit out twenties? Or even a rat reporter photo submission app? C'mon people, let's get creative.
